Philip Seymour Hoffman withdrew a total of $1,200 from an ATM at a supermarket near his New York City apartment the night before he was found lifeless in his bathroom with a syringe still in his left arm, sources told NBC News.

Drum fish, which are bottom feeders, are not sought by fishermen, he added, and fishing was not banned as a precaution. "Right now it's fine to fish," KTHV quoted Stephens as saying. "If you go out there you can still fish for bass and crappie, catfish, it will be fine. Obviously don't eat the dead fish."

Fish were still floating on the same stretch of river as of Monday morning.

Stephens said that nature will be doing the cleanup. "We'll have raccoon and birds and things like that will take care of it so there is really no cleanup, it's really too big. It's contained along the river channel."

David Lyons, the head of a local chapter of the Sierra Club, told msnbc.com that he was "waiting for the results of the pathology and toxicology tests before I make any judgments about the bird and fish kills.

"So far, the evidence does not suggest that pollution contributed to either the bird or fish kill," he added. "If the test results indicate that contaminants were responsible, then local environmental groups will likely have several questions and concerns about the two events."

Transcript of: Massive fish kill deepens dead bird mystery

BRIAN WILLIAMS, anchor:We mentioned this earlier and we're back now with the puzzling story of a massive kill of wildlife in the state of
Arkansas
. Birds falling out of the sky, the result of some sort of trauma, and fish found
dead in the water
, thousands of them in separate incidents in the same state. We get our report tonight from
NBC
's
Janet Shamlian
in
Beebe
,
Arkansas
.

JANET SHAMLIAN reporting:They rain down on a small
Arkansas
town like a scene from a horror movie. Thousands of dead black birds on front lawns, and so many in the street, drivers could barely avoid them.

Mr. CHARLES MOORE (Resident):I went out to get the paper and I looked and I said, 'Wait a minute, what is this?' And there were birds all -- we probably had 14 or 15 just in the front yard.

SHAMLIAN:As many as 5,000 bird carcasses littered across a one-mile radius after dropping from the sky on
New Year's Eve
. So you had them just about everywhere?

Mr. MOORE:Oh, my goodness. They were
all over the place
.

SHAMLIAN:What could have caused it? As the state veterinarian examined the birds today, theories have run the gambit from their being hit by lightning or high altitude hail to being spooked to death by
New Year's Eve
fireworks.

Dr. GEORGE BADLEY (Arkansas State Veterinarian):They do have a lot of trauma. I mean, they were like they were hit by something.

SHAMLIAN:Beyond the birds and adding to the mystery, a massive
fish kill
also here in
Arkansas
just one day earlier. As many as 100,000 drum fish dead along a 20-mile stretch of the
Arkansas River
. It's 100 miles from the
dead birds
but the
Internet
was ripe with conspiracy theories. One
Twitter
user writing, "5,000
dead birds
, now 100,000 dead fish, definitely an alien invasion happening in
Arkansas
." The experts call it coincidence.

Mr. KEITH STEPHENS (Arkansas Fish and Game Commission):Extremely unusual, having two events like this at practically the same time. We don't think that there's any connection whatsoever.

SHAMLIAN:Wildlife officials say the fish likely died of disease, not a pollutant. Too alarming. Some have called biblical type of events that have many residents wondering what's next.
